ASTM F879-02 - 10.6.2002
 
1. Scope

1.1 This specification covers the chemical and mechanical requirements for stainless steel inch hexagon socket button (SBHCS) and flat countersunk (SFHCS) head cap screws with nominal thread 0.060 through 0.625 in. intended for use in applications requiring general corrosion resistance.

1.2 The following two conditions are covered:

1.2.1 Austenitic alloy condition AF in an annealed condition at 85 ksi maximum and

1.2.2 Austenitic alloy condition CW in a cold-worked condition at 95 ksi minimum.

1.3 The following precautionary caveat pertains only to the test method portion, Section 12, of this specification: This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
